Namespace: System.Text.RegularExpressions

The System.Text.RegularExpressions namespace contains classes that provide access to the .NET Framework regular expression engine. The namespace provides regular expression functionality that may be used from any platform or language that runs within the Microsoft .NET Framework.

Members of System.Text.RegularExpressions Namespace

Class	Description
class Capture	Represents the results from a single subexpression capture. represents one substring for a single successful capture.
class CaptureCollection	Represents a sequence of capture substrings. returns the set of captures done by a single capturing group.
class Group	represents the results from a single capturing group. A capturing group can capture zero, one, or more strings in a single match because of quantifiers, so supplies a collection of Capture objects.
class GroupCollection	Represents a collection of captured groups. returns the set of captured groups in a single match.
class Match	Represents the results from a single regular expression match.
class MatchCollection	Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.
class Regex	Represents an immutable regular expression.
class RegexCompilationInfo	Provides information that the compiler uses to compile a regular expression to a stand-alone assembly.
class RegexRunner	This type supports the .NET Framework infrastructure and is not intended to be used directly from your code. Supports the Shared Source CLI infrastructure and is not intended to be used directly from your code
class RegexRunnerFactory	This type supports the .NET Framework infrastructure and is not intended to be used directly from your code. Supports the Shared Source CLI infrastructure and is not intended to be used directly from your code

Delegate	Description
delegate MatchEvaluator	The delegate that is called each time a regular expression match is found during a Regex.Replace operation.

Enumeration	Description
enumeration RegexOptions	Provides enumerated values to use to set regular expression options.
